REGISTER CONSTRUCTION.

Application filed September 13, 1926. Serial No. 135,219.

This invention relates generally to heating apparatus and refers moreparticularly to hot air registers.

One of the essential objects of the invention is to provide an eflicientregister of this type that is simple in construction, neat in appearanceand that may be easily and quickly installed, for instance in the floorof a vehicle body.

Another object is to provide aregister in which the hot air from theheater is deflected in such a way by a baflle in the register that asubstantially uniform distribution of hot air will be obtainedt-hroughthe outlet openings at the top of the register.

A further object'is to provide a registerhaving means at the bottomthereof, preferably associated with the air deflecting means, forpermitting dirt and other foreign matter collecting into the register tobe discharged therefrom.

\Vith these and other objects in view, the invent-1011 resides incert-am novel features of construction, combinations and arrangements ofparts as will be more fully described and particularly pointed out inthe appended claims.

In the accompanying drawing:

Figure l is a vertical sectional view through a register embodying myinvention applied to a floor of a vehicle body.

Figure 2 is a perspective view of the top or cover of the register.

Figure 3 is a perspective view of the body of the register.

Figure 4 is a bottom plan view of the register. V

Figure 5 is a view similar to Figure 4 but showing a slightly modifiedconstruct-ion.

Figure 6 is a top plan view of a slightly modified form of cover.

Figure 7 is a transverse sectional view through the construction shownin Figure 6.

Figure 8 is a fragmentary sectional View of the cover shown in Figures 6and 7 applied to the lateral flange of the register body.

Referring now to the drawings 1 is a register embodying my inventionmounted in the floor 2 of a vehicle body. As shown, this register has asubstantially cup-shaped body 3 and an apertured cover 4t and is,adapted to be supplied with hot air by means of a conduit 5 that leadsfrom a suitable heater (not shown). \Vith this construction the controlmeans such as a valve and the like for regulating the flow of airthrough the register is preferably located in the conduit 5 at a pointremote from the register.

To provide an eflicient construction, one side of the body is providedwit-h an inlet opening 6 through which the hot air from the conduit 5 isadapted to flow into the register, while the open upper end of the bodyis preferably flared as shown at 7 and is provided with the laterallyextending attaching flange 8. As shown in Figure 1, this flange issecured by suitable headed elements such as thescrew 9 to the floor 2 ofthe vehicle body and sci-ms as a hearing or seat for the cover 4. Anysuitable means such as the screws 10 may be used for securing the coverL to the flange 8. Preferably these screws extend upwardly through theflange 8 and 'threadedly'engage suitable enlargements 11 of thedepending flange 12 of the cover.

Thus these securing elements 10 areefiectlvely concealed when theregister is installed. If desired, a suitable annulus or rlng 13 may beused to conceal the edges of the carpet l4 surrounding the register; In

practice this ring 14' is provided with a neat ffinish and is preferablyheld in place by suitable pins or lugs 16 that project laterally fromthe'depending flange 12 of the cover.

In order that the air will be properly distributed through the apertures4 in the cover 4, I have provided a baflle 17 which is secured in thebody 3, preferably in rear of the inlet opening 6 and approximatelymidway between the front and rear walls of the body for deflectinglongitudinally of the body the hot air admitted through the inletopening 6. lVith this arrangement the hot air from the heater enteringthe register will be divided by the baflle 17 so that a portion of theair will flow upwardly in front of the baifle to the apertures in thecover, while the remainder of the air will flow beneath the battle,thence upwardly in rear thereof to the apertures 4 in the cover 4.

In order that dirt and other foreign matter collecting in the body ofthe register, may

be discharged therefrom, the bottom 19 of the door 21 and bafile 17. Ifdesired the ac the bottom 19 and door 21.

tuating means may be a coil spring having certain of the convolutions 23and 2% respectively thereof sleeved upon the hinge pintle 2'5 and havinglaterally extending arm portions 26 and 27 respectively bearing against(See Fig. 5.) Thus the door 21 may be pressed downwardly against thetension of the spring means to discharge dirt by merely inserting asuitable implement or tool through one of the apertures in the cover 4andthen pressing the said implement downwardly against the door 21 touncover the outlet opening 20. Inasmuch as the baflle 17 directs the hotair longitudinally of the body, it will be apparent that a portion ofsuch air will remove the dirt, etc. from the body through the opening20.

In- Figures 6 to 8 inclusive I have shown a slight modification in whichthe depending flange 1-2 of the cover isprovided at spaced 7 points withdepending lugs 30 which extend through suitable openings 31 in theflange 8 and are riveted thereto.

dispensed with entirely. Thus, a permanent and veryrigid joint isprovided.

lVhi-le it is believed thatfrom the foregoing description, the natureand advantage of my invention will be-readilyapparent, I desire to vhave it understood that I do not limit myself to what- 1s herein shownand described and that such changes may be resorted to when desired asfall within the scope of what is claimed.

hat I claim as myinvention is 1. An air re 'lster of the class describedcomprising a body having an inlet opening mally closing one of saidoutlet openings so that a portion of the air deflected by said bafiletowards said opening will flow around L said baffle toward the other ofsaid outlet openings.

2. An air register 'of the class described comprising a substantiallycup-shaped body having a lateralinlet opening for air and having; anoutlet for dirt and air at the bottom thereof below said opening, aspring actuated door normally closing said outlet open-- ing, and abaifle in said body for deflecting towards said dirtroutlet opening aportion of the air admittedto the body through said inlet opening.

3. The combination with the flooring of a vehicle body having an openingtherein, of an air register comprising a substantially cupshaped bod-yinsaid opening and having a lateral inlet openingfor air below theflooring and having an-outlet for dirt and air in the bottom. thereofbelow said lnlet opening,

lVith such construe t1ons,-th'e screws 10- and enlargements 11 are adoor normally closing said outlet opening, and a baffle extendinglongitudinally of the body in rear of the inlet opening fordeflectingtowards said dirt out-let a portion of the air admitted to,said body through the inlet a substantially cup-shaped body and an aper-I tured cover having a depending flange provided with an: enlargement,the body having a lateral flange servingas a; bearing for the dependingflange of the cover, and a concealed connection between said cover andbody including an element extending through the flange and engaging saidenlargement.
